Captivity of Melkor

Captivity of Melkor was the term of three ages for which Melkor was held prisoner by the Valar in Valinor.[1] At the end of the third age of his captivity, Manwë released Melkor,[2] but he turned back to darkness, destroying the Two Trees and fleeing back to his strongholds in the north of Middle-earth with the Silmarils.[3]
